ORA-31640: unable to open dump file ORA-19505 ORA-27037

环境: 11.2.0.4 Rac双节点 ,准备在单节点下导入报错
Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA
ORA-31693: Table data object "GS"."JC_SALESMAN_DATA" failed to load/unload and is being skipped due to error:
ORA-31640: unable to open dump file "/home/oracle/dump/xxxx.dmp" for read
ORA-19505: failed to identify file "/home/oracle/dump/xxxx.dmp"
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

正确导入语句:
impdp \'/ as sysdba\' schemas=gs directory=my_dump dumpfile=xxxx.dmp logfile=xxx.log parallel=2 TABLE_EXISTS_ACTION=replace  CLUSTER=N

检查了一下文件权限和路径都是正确的
Mos参考文档:DataPump Import With PARALLEL > 1 In RAC Environment Fails With Errors ORA-29913 ORA-31640 ORA-19505 ORA-27037 (文档 ID 1173765.1)

 It is caused by a RAC instance not having physical access to the dump file (as indicated by the DIRECTORY parameter) and using a parallel degree > 1. The problem with this setup is that the PQ/PX slaves are not constrained to the RAC instance from which the IMPDP operation has been started, and when such a PQ/PX slave doesn't have access to the dump file, the errors are raised.

参数CLUSTER : Default=Y  在本案中设置为N即可顺利导入


若有正在导入的impdp语句，需要先停掉
1: ps -ef |grep impdp  找到进程号先kill
2:查询job
select * from dba_datapump_jobs;

3: 登录进去impdp \'/ as sysdba\' attach= SYS_IMPORT_SCHEMA_01
kill_job停止响应job即可
